Discover the Magic of Wild Blueberries
Ah, wild blueberries – they truly are in a league of their own. Unlike their larger, more common cultivated cousins, these tiny powerhouses deliver an intensely concentrated flavor that is both sweeter and tangier, making them a culinary delight. Their small size means more skin per berry, which contributes to their robust taste and, notably, a higher concentration of beneficial compounds. In fact, wild blueberries are celebrated for their exceptional nutritional profile, reportedly containing twice the antioxidants of regular blueberries and boasting the highest antioxidant capacity among over 20 other fruits. This makes them not only a delicious choice but also a remarkably healthy one.
During their fleeting season, we find endless ways to incorporate these jewels into our meals. From a simple sprinkle over creamy yogurt, crunchy cereal, or warm oatmeal to elevating desserts like crêpes and ice cream, their versatility is unmatched. They are equally magnificent baked into muffins, sweet breads, and cakes – and yes, they even add a sophisticated touch to cocktails! For many, the ultimate indulgence is a homemade wild blueberry pie, especially when you’ve had the pleasure of picking the fruit yourself. There’s an undeniable satisfaction in tasting that extraordinary freshness and knowing you’re enjoying a truly special treat.
Introducing Wild Blueberry Financiers: Elegance Made Easy
This year, inspired by the bountiful harvest, I sought a new way to showcase the intense flavor of my yearly wild blueberry crop. Financiers, with their reputation as light, delicate French cakes, immediately came to mind. Their elegant appearance belies their surprising ease of preparation, making them the perfect vehicle for these exceptional berries. Imagine serving a batch of these golden-edged financiers, still warm from the oven, to unexpected guests – they are guaranteed to impress with minimal effort.
Our Wild Blueberry Financiers recipe features the exquisite combination of hazelnuts and brown butter. The subtle, earthy notes of toasted hazelnuts perfectly complement the deep, nutty aroma and flavor imparted by the brown butter, creating a harmonious and truly addictive taste experience. While this recipe highlights the hazelnut-brown butter pairing, it’s also wonderfully adaptable. You could certainly prepare these financiers by simply melting the butter (without browning) and substituting ground almonds for hazelnuts, yielding a classic financier profile. Furthermore, feel free to experiment with other fresh fruits as toppings – even regular blueberries will work beautifully. However, if you have access to the incomparable wild variety, I wholeheartedly encourage you to indulge in their unique charm. And remember, stock up during peak season! Freezing any leftover wild blueberries means you can savor these delightful financiers and other berry treats all winter long.
The Art of Brown Butter (Beurre Noisette)
One of the secret ingredients that elevates these financiers to gourmet status is brown butter, also known by its French name, beurre noisette (literally “hazelnut butter,” a nod to its beautiful color and nutty aroma). This simple yet transformative technique adds an incredible depth of flavor to both sweet and savory dishes. It’s an easier process than you might think and brings a world of rich, caramelized notes to your baking.
To create brown butter, you gently cook unsalted butter over medium heat. As the butter melts, the water content evaporates, and the milk solids begin to separate and toast, turning a lovely golden-brown color. This process releases a truly intoxicating, deeply nutty aroma—reminiscent of toasted hazelnuts or caramel. It’s crucial to watch it closely, as it can go from perfectly browned to burned very quickly. The key is to remove it from the heat once those golden-brown flecks appear at the bottom of the pan and the fragrance fills your kitchen. This simple step infuses the financiers with an unparalleled richness and complexity, transforming them from good to truly extraordinary.

Wild Blueberry Financiers Recipe
Ingredients
- 1/2 cup (125 ml) unsalted butter
- 1 cup (250 ml) hazelnuts, lightly toasted and peeled (see note below for instructions)
- 1/2 cup (125 ml) all-purpose flour
- 1/2 cup (125 ml) granulated sugar
- 1/2 cup (125 ml) light brown sugar, packed
- 1/2 tsp (2 ml) baking powder
- 4 large egg whites (from large eggs)
- 1 cup (250 ml) wild blueberries, freshly washed and gently patted dry (or frozen wild blueberries, unthawed for convenience)
Instructions
-
Prepare your oven and muffin pans: Preheat your oven to 350°F (175°C). Lightly grease standard muffin pans (or financier molds, if you have them, see notes) with cooking spray or softened butter. Then, dust them with a light coating of all-purpose flour, tapping out any excess. This ensures easy release. Set the prepared pans aside.
-
Make the brown butter: In a small, light-colored stainless steel pot (this makes it easier to observe the color change), melt the unsalted butter over medium heat. Continue cooking, stirring or swirling the pot occasionally, as the butter simmers. You’ll notice bubbles forming as the water content evaporates. If the bubbles become too dense and obstruct your view of the milk solids at the bottom, simply lift the pot off the heat for a few seconds until they recede, then return it to the burner.
The brown butter is ready when the milk solids at the bottom of the pot turn a delicate light brown, resembling toasted hazelnut shells, and the entire mixture emits a wonderfully rich, nutty aroma. Immediately remove the butter from the heat and pour it into a small, heat-proof bowl to stop the cooking process. Allow it to cool for approximately 10 minutes.

-
Prepare the financier batter: In the bowl of a food processor, combine the toasted hazelnuts and all-purpose flour. Pulse until the mixture is finely ground and resembles a coarse, sandy powder. Transfer this mixture to a large mixing bowl. Add the granulated sugar, packed light brown sugar, and baking powder, then whisk thoroughly to combine all the dry ingredients. Pour in the four large egg whites and whisk until they are fully incorporated, resulting in a thick and slightly sticky batter. Finally, gently fold in the cooled brown butter until just combined. At this stage, the financier batter can be stored in an airtight container in the refrigerator for up to two days, making it perfect for preparing ahead.
-
Bake the financiers: Once you are ready to bake, drop approximately one tablespoonful of the batter into each prepared muffin cup. Evenly sprinkle each financier with a generous teaspoonful of wild blueberries. Bake for 16 minutes, rotating the pan halfway through the baking time to ensure even browning, until the edges of the financiers are beautifully golden brown and the centers are set. Allow the financiers to cool in the pan for about 10 minutes before carefully transferring them to a wire cooling rack to cool completely.
STORAGE
-
Storing your financiers: Store these delicate French cakes in an airtight container at room temperature for up to three days to maintain their freshness. For longer storage, financiers can be frozen for several weeks; simply thaw them at room temperature for 15 to 20 minutes before serving. For the most exquisite flavor and texture, always allow your financiers to come back to room temperature before enjoying. You can also briefly warm them in a low oven for a “fresh from the oven” experience.
Notes for Perfect Financiers
- This recipe is designed for regular 12-cup muffin pans, as they are a common kitchen staple. For an authentic financier shape, you can use specialty financier molds. Mini-muffin pans are also an option for bite-sized treats. Just remember to adjust your baking time accordingly when using different-sized molds, as smaller financiers will bake faster.
- Baking in batches: If you only own one muffin pan, don’t worry! You can easily bake the financiers in successive batches. The prepared financier batter holds beautifully and can be refrigerated for up to 2 days. If you’re baking batter that has been chilled, simply add an extra 2-3 minutes to the standard baking time to account for the colder dough.
- Choosing your pot for brown butter: It’s highly recommended to use a stainless steel saucepan when making brown butter. The pale metal interior provides excellent contrast, allowing you to clearly see the milk solids changing color at the bottom, which is crucial for achieving that perfect nutty golden hue without burning. If you’re using a dark-colored non-stick pan, you can still achieve great results by frequently using a spoon to scoop up some butter from the bottom and check the color of the milk solids.
- How to toast and peel hazelnuts for optimal flavor: Hazelnuts truly shine when lightly toasted and peeled. To do this, spread your hazelnuts in a single layer on a baking tray. Bake them at 350°F (170°C) for about 10-15 minutes, giving the tray a good shake every five minutes to ensure even toasting. You’ll know they’re ready when their skins appear shiny and crackled, and you can smell their fragrant aroma. Immediately remove them from the oven and transfer them to a clean dish towel. Gather the towel into a bundle and rub the hazelnuts vigorously against each other inside the towel. This friction will help remove most of the papery skins. Open the towel and pick out the peeled hazelnuts. Don’t worry if a few stubborn bits of skin remain; they won’t affect the flavor or texture. Store your peeled hazelnuts in an airtight container in the fridge until you’re ready to use them in your recipe.
